It offers 100µV of offset, very low drift (1µV/°C) over temperature, low bias currents, and very low flicker noise of 400nVPP (0.1Hz to 10Hz). It operates over a very wide supply voltage range of ±4V to ±18V on a low 4.5mA supply current. A dual version is also available for the OPA827 family. Excellent ac characteristics, such as 18MHz gain bandwidth (GBW) and 22V/µs slew rate, and precision dc characteristics make the OPA827 series well-suited for a wide range of applications such as 16- to 18-bit data acquisition systems, transimpedance (I/V−conversion) amplifiers, filters, precision ±10V front-ends, and professional audio applications. The single version (OPA827) is available in both MSOP-8 and standard SO-8 surface-mount packages. The dual version (OPA2827) is available in the small TSSOP-8 and in the standard SO-8 packages. All versions are specified from −40°C to +125°C.

Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.7V beyond the supply rails should be current-limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package. This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
